They said the sunny weekends are a double edged sword because they love to see people enjoying the open spaces of the city, but they're not happy that a lot of people simply don't clean up after themselves. "There was so much trash and it seems like there's a lot of people from out of town and stuff who come to visit for the day and don't really take care of it," Andrew Scarani said.

"We are hoping to find a trash on the exterior of the park and if not, it's going home with us," Redwood City resident Lauri Badar said.

Badar and her family packed up their trash and hauled it to one of the trash bins on the outer perimeter of the park.

There are a few temporary signs reminding people to take their trash with them, but there only a few bins inside the park, so people have to walk all the way out to throw they trash away.
